Step by step guide on how to replace air flow sensor yourself.
Estimated time: 20 mins Difficulty: Easy/Medium
Always remember to disconnect the battery when working with electrical parts. Disconnect the negative terminal to avoid sparks.
The air flow sensor is located right above the air filter on the driver side of the vehicle. It is connected to the air hose at one end and the air box at the other. To disconnect the electrical connection you might need a small flat headed screwdriver to pry the connection free. Before trying this you might be able to remove it by hand.
Using the screwdriver you will want to loosen up two hose clamps by unscrewing the screw holding each hose in place. To free up the air flow sensor you will need to twist the air hose free. If this is a bit stiff you can use the screwdriver to prize it free. Once it is free tuck the hose out of the way.
Pull on the air flow sensor, twisting it free from the air box. Once you have the old air flow sensor free, you will need to remove the rubber connecting ring around the sensor, as you will need to the new air flow sensor to the other parts. Again you might want to use the screwdriver to prize it free.
Fitting the new air flow sensor
Now it’s time to fit the new air flow sensor.
Begin by placing the rubber connecting ring you just took off the old sensor onto the air box, sliding it into place.
Now connect the sensor to the air box by connecting it to the rubber connecting ring. Make sure they are pushed together firmly to ensure a tight connection.
Connect the air hose to the other end of the air flow sensor and push them together firmly to ensure a good connection. Once they are connected together at both ends tighten the two screws on both the clamps.
Connect the electrical connection to the new air flow sensor and this completes the air flow sensor installation.
